'Cyrano' has sparse pubescence at the base of the lightsprout while it is dense for 'Yukon Gold'. The tip of the lightsprout of 'Cyrano' has a very strong intensity of anthocyanin colouration and medium to dense pubescence while the tip of the light sprout of 'Yukon Gold' has medium intensity of anthocyanin with sparse pubescence. 'Cyrano' has anthocyanin colouration only at the base of the stem while it is along the entire stem in 'Yukon Gold'. The leaf of 'Cyrano' has intermediate openness while it is open in 'Yukon Gold'. 'Cyrano' has medium to strong glossiness on the upper side of the leaflet while it is dull to medium glossiness in 'Yukon Gold'. The plant height of 'Cyrano' is shorter than in 'Yukon Gold'.

Origin & Breeding History: The origin of 'Cyrano' is the result of a cross made in 1991 between 'Goldstar' and HO86E423 at HZPC, Metslawier, The Netherlands. The selection criteria included yield, external quality and resistance to diseases and pests.

Tests & Trials: Tests and trials were conducted during the 2011 growing season in Drummond, New Brunswick. Plots consisted of 60 plants grown in a single row with a row length of 18.5 meters and a row spacing of 0.9 meters.
